Image display

Abstract

To provide a reliable high brightness and definition image display by inhibiting a possible increase in fan noise and promoting cooling of an upper, hot portion of a display panel module, various boards, and image processing electronic components, an image display includes a flat display panel module, a display surface side cover on a display surface side of the display panel module, a non display surface side cover on a non display surface side of the display panel module, a display driving board, a power supply board, and a cooling fan, wherein a case of the cooling fan is larger than a distance between the display panel module and the non display surface side cover in an area where the cooling fan is installed, and a first end of the case of the cooling fan closer to the non display surface-side cover is positioned above a second end of the case closer to the display panel module.

The invention claimed is: 
     
       1. An image display comprising a panel display module of flat type, an image display surface side cover arranged at an image display surface side of the panel display module, a non image display surface side cover arranged at an non image display surface side of the panel display module opposite to the image display surface side in a thickness direction of the panel display module, a display drive substrate, an electric power source substrate, and at least one cooling fan,
 wherein the at least one cooling fan has a rotating impeller and a case receiving therein the rotating impeller, a size of the case in a first direction perpendicular to a rotational axis of the rotating impeller being greater than a distance in a second direction perpendicular to a surface of the panel display module at the non image display surface side between the surface of the panel display module at the non image display surface side and the non image display surface side cover at a position where the at least one cooling fan is arranged, in a cross sectional view taken along a vertical imaginary plane perpendicular to the surface of the panel display module at the non image display surface side, and 
 wherein the at least one cooling fan is arranged so that one end of the exhaust side surface is closer to the panel display module than the non image display surface side cover while another end of the exhaust side surface is closer to the non image display surface side cover than the panel display module, and the another end of the case which is closer to the non image display surface side cover and opposite to the end of the case in the first direction, is arranged at an upper position with respect to the one end of the case which is closer to the panel display module, in the cross sectional view, so that an air flowing out of the at least one cooling fan is directed toward the panel display module. 
 
     
     
       2. The image display according to  claim 1 , wherein the at least one cooling fan is arranged at an upper position with respect to the display drive substrate and the electric power source substrate. 
     
     
       3. The image display according to  claim 1 , wherein the at least one cooling fan is arranged at an upper position with respect to a vertically half position of the panel display module between the display drive substrate and the electric power source substrate. 
     
     
       4. The image display according to  claim 1 , wherein a plurality of image processing electronic parts are arranged in the vicinity of an upper end of the panel display module. 
     
     
       5. The image display according to  claim 1 , wherein the non image display surface side cover has an opening prevented from being arranged at a rear side of an inlet of the cooling fan.
